feat(sub): clash row + reorganise SubPage around Subscription info

ClientInfoModal:
- Add a Clash / Mihomo row to the subscription section, gated on
  subClashEnable + subClashURI from /panel/setting/defaultSettings.
  Defaults payload schema is widened to carry subClashURI/subClashEnable.

SubPage:
- Drop the rectangular QR-codes header that used to sit at the very
  top of the card. The subscription info table now leads, followed by
  Divider("Copy URL") + per-protocol link rows (already converted to
  the compact ClientInfoModal pattern), then a new Divider("Subscription")
  + compact rows for the SUB / JSON / CLASH URLs with copy + QR-popover
  actions. The apps dropdown row remains the footer.

CSS clean-up: removed the now-unused .qr-row/.qr-col/.qr-box/.qr-code
rules; kept .qr-tag and trimmed the info-table top gap. Added a
.sub-link-anchor underline-on-hover style for the new URL rows.
